Fun with CurrentCost

Five years after the cool kids first started jumping on the bandwagon, I’ve got myself a CurrentCost CC128 (Southern Electric send them to some customers for free, it seems – e.g. my granddad who didn’t want it).

The parser for the XML output of the device I’m using is this one – just swap “COM20″ for “/dev/ttyUSB0″ in their testrun script and fix it to ignore empty lines read from the serial port, and you’re in business. I then hackdapted this RRDTool tutorial to plot the graphs.
